The Infection spreads...

It seems that although I had isolated the infected black neon tetra, this had not stopped the fungal infected to spread. To my dissapointment, I spotted white spots on my Cardinal tetras this morning

I quickly changed the tank water and added salt but a very minimal amount of Tertracycline. The fishes seemed to be stabilizing and were still active an hour later. I just hope for the best till next morning.
